This is how the Rocketroll project works

by

Artemis II has been an example of how far space travel can go. So far that there will come a time when the technologies currently used to propel ships will be insufficient. There is no point in using solar energy if we move too far from the Sun or travel to the Moon, with 14-day nights. Nor is it useful to use the best fuel if the trip is going to be so long, so far and with so much load that refueling needs would be unfeasible. For this reason, nuclear propulsion has been considered for some time to take ships where they cannot go today. The European Space Agency (ESA) has also jumped on that bandwagon and has already carried out its first studies. An order for three consortia. The ESA just announced the first results of the Rocketroll project, which has asked three independent consortia to design an approach to use nuclear electric propulsion in European space missions. This is something that other space agencies, such as NASA, have already begun to study, but in European territory work had not yet been done on this specific issue. Thermonuclear propulsion vs nuclear-electric propulsion. In fact, nuclear propulsion for spacecraft had already been studied in Europe. That is the key to the Alumni project, presented by ESA last year. The difference is that in that case a thermonuclear propulsion system was designed. That is, a reactor in which nuclear fission generates heat that is used to heat a fluid that serves as a propellant. What has been studied in Rocketroll is different, since nuclear fission generates electricity, which is supplied to a series of electric motors. Each one has its advantages. In absolute terms, thermonuclear propulsion is more powerful. However, it is accompanied by technical problems, such as storing a sufficient amount of propellant. Plus, it’s very expensive. The other option is cheaper and, accompanied by some chemical propulsion, is just as powerful. That is why ESA is so interested in having its ships work with this mechanism. Three consortia, three proposals. Three multidisciplinary consortia have participated in this project: Tractebel, CNRS and OHB Czech Space. Each has made a proposal that would be incorporated into the entire system. For example, the first consortium has proposed using enriched uranium as a generator of nuclear power. Uranium-238 is the most abundant in nature, but it is not fissile. This means that a nuclear fission chain reaction cannot be maintained from it. Nuclear fission is the process by which energy is obtained in nuclear reactors, so it is of no use to us. On the other hand, Uranium-235 is fissile. Enriched uranium is richer in this isotope, so it can be used in a nuclear reactor. Compared to other options, such as Plutonium-239, Tractebel considers that this is better. For its part, CNRS proposes using a molten salt reactor. That is, a reactor in which this type of salts are used as coolant and/or fuel to trigger nuclear fission. Finally, the third consortium proposes that the ships be larger to optimize the results. Scheme of the alumni nuclear thermal propulsion system (Image rotated) A safe option. All consortia conclude that nuclear-electric propulsion can open new paths for space exploration. This is great news, but we may have doubts about its safety. Before them, they remember that it is a risk-free process. The uranium that would be activated remains inert and is only activated, to trigger nuclear fission, once it is in orbit. There would be no risks while handling the ships on Earth. In addition, shields are used so that astronauts and spacecraft cargo are not at risk when the reaction is triggered. We must not forget that space is also a large source of radiationso ships must be properly protected. Next steps. This first step by Rocketroll has been little more than a brainstorm. There is still quite a way to go. For example, each system will have to be studied separately, from the nuclear reactor to the radiation shield, including the energy conversion system, the thermal heating and cooling system and the electric thrusters. For all this, ESA has already formed a nuclear propulsion working group that will oversee the design and construction of subscale hardware. There will also be laboratory tests to confirm that everything is working properly before even thinking about testing the system in space. This technology may be the future, but it must be tested slowly.

The largest naval project in German history since World War II is turning out to be a crazy disaster

by

In Europe, large military programs often take more than a decade to be completed and, in many cases, end up costing several times more than initially anticipated. It is not uncommon for complex projects to accumulate thousands of technical requirements and go through multiple reviews before reaching production. In this context, some plans are born as emblems of modernization… and end up becoming examples of how difficult it is to bring them to fruition. From something historic to something unsustainable. He program F126 was born as the great symbol of German rearmament and largest naval project of the country since the Second World War, but over time it has become quite the opposite: an example of how an ambitious plan can derail to the point of collapse. Conceived as a latest generation frigateflexible and prepared for decades of service, the project has not only accumulated delays and cost overrunsbut has called into question Germany’s ability to execute large military programs at a time when it aspires to lead European defense. Technical errors and chaos. He told in an extensive report the financial times that the origin of the problem seems as modern as it is devastating: a failed bet on a new software design that was not ready for a project of this scale. What should have been an advanced tool ended up generating cascading errors, from cables incorrectly located on the plans to steel parts manufactured with incorrect shapes, forcing manual corrections and slowing down the entire production. The result was a system that was moving at just a fraction of its planned pace, with delays that pushed the initial delivery several years later than planned. A culture shock. It turns out that the problem was not just technical. Apparently, the media reported that the project was trapped in a deep shock between the Dutch shipyard’s way of working and the German contracting system, known for its extreme rigidity. Thousands of specifications detailed even the smallest elements, while approval processes were they dragged on for months within a complex bureaucracy that required paper documentation and rejected even plans in English. This combination made collaboration a slow, frustrating, and, in many cases, unproductive process. Skyrocketing costs and limit decisions. As the problems piled up, so did made the invoice: The project, initially valued in the billions, began to go off track with significant cost overruns and structural delays. As it is, Germany now faces critical decisions ranging from replacing the main contractor to accepting billions already invested. as irrecoverable losses. At the same time, faster but less ambitious alternative solutions are being studied, reflecting the extent to which the original project has lost credibility. Notice to sailors of rearmament. If you like, the case of the F126 goes beyond a simple industrial failure: it reveals the limits of European military cooperation even among closely integrated countries and raises questions about the continent’s ability to implement complex joint programs. In a context of increasing of defense spending and increasing strategic pressure, the project has become a clear warning: It is not enough to invest more, you also have to know how to manage better. Because otherwise, even the most important projects can end up being, as in this case, a costly and lengthy example of what not to do.

NASA has put a Spaniard in charge of the project for its future lunar base: Carlos García-Galán from Malaga

by

Dressed in a jacket, light blue shirt and gold tie, Carlos García-Galán He did not occupy another chair at the NASA conference held in Washington. Escorted by the administrator Jared Isaacman and other top-level officials, the engineer from Malaga spoke before the press in the middle of the presentation of the agency’s new lunar turn. His presence at that time placed him at the forefront of a roadmap that redefines NASA’s priorities on the Moon. The context of that scene helps understand its relevance. Hours before,Isaacman had presented a roadmap that changes the focus of the agency. It is no longer just about returning to the Moon, but about establishing a sustained presence on its surface. The proposal involves deploying in three phases the initial elements of a permanent lunar base, with stable infrastructure and a logic that is more industrial than experimental. The man from Malaga who now pilots the Moon Base program This change of course also redefines the role of those who must execute it. In this context appears García-Galán, whose official position within NASA is “executive program” at the lunar base. This is a high-level management position, responsible for coordinate and guide program development, not an operational role on the ground. His role will be to lead the project from the agency structure, not to direct a facility on the lunar surface. García-Galán, remember, is not a newcomer, but an engineer who has developed his career within NASA and has been assuming responsibilities for years to get to this point. His presence in the announcement is linked to that trajectory, which now places him in one of the great bets of the US space agency at this stage. His career within NASA helps to understand why he has come this far. Before this appointment, García-Galán, according to LinkedInheld the position of “deputy manager” of the Gateway program, until now a relevant piece in the agency’s lunar architecture. With more than 27 years of experience In manned space flights, he has worked on the design, integration and operation of complex systems, participating in programs such as the International Space Station and the Orion spacecraft. His experience at Gateway also helps explain this appointment. In that program, García-Galán was involved in integration and management tasks within an environment with multiple partners and components. The new approach towards a lunar base requires precisely this ability to order diverse pieces, from missions to infrastructure, something that fits with the profile that has been developed within the agency in recent years. The program that he will now supervise is divided into several phases with a common objective: establishing a sustained presence on the lunar surface. NASA proposes a sequence of missions that will go deploying infrastructurefrom mobility and energy systems to communications networks and habitats. The idea is to advance progressively towards a base capable of sustaining longer-term human stays.

Microsoft killed the traditional Xbox by saying that everything was an Xbox. Now he wants to resurrect it with Project Helix

by

Microsoft has quietly withdrawn its “This is an Xbox” campaign, the initiative with which it had spent 16 months trying to convince the world that any device (television, mobile phone, tablet) It was technically an Xbox.. The deletion coincides with the replacement at the top managementthe debut of Project Helix at GDC and a market paradox: Sony and Microsoft have become, at the same time, the main defenders of the concept “a console is a console.” The campaign. The series of ‘This is an Xbox’ ads were launched under the presidency of Sarah Bond and functioned as the great manifesto of the post-hardware era of Microsoft Gaming. Now it has disappeared without an official statement: the blog entry that opened it on Xbox Wire gives error 404and searching for the term in the official Xbox news repository only returns one article about ROG Xbox Ally. The files indicate that the page was still accessible on March 1, 2026. What was it about? The idea behind “This is an Xbox” was, in theory, reasonable: expand the ecosystem beyond its own hardware, bet on the streaming in the cloud as a gateway and normalize that playing Xbox did not require purchasing an Xbox console. The problem is that the argument, taken to its extreme, destroyed the reason for the hardware. The campaign generated more confusion than interest, with fans wondering why they would buy an Xbox if the titles were available on any platform. The rejection. Apparentlythe initiative was not well received internally, and the company made some strategic lurches. For example, the announcement of an Xbox mobile store in summer 2024 never materialized. A few months later, with the arrival of Asha Sharma as the new CEO of Microsoft Gaming and the departure of Phil Spencer and Sarah Bond, the campaign has ended up being withdrawn. The phrase with which Sharma summed up this new change of direction speaks for itself: “The plan is the plan until it isn’t“. More from Helix. The same day that the 404 of “This is an Xbox” was discovered, Microsoft had a presence at GDC 2026 with the Developer Summit dedicated to Project Helix. Jason Ronald, vice president of Next Generation at Xbox, presented the technical details of the upcoming hardware: a console powered by a custom AMD SoC, co-designed for next-generation DirectX and FSR technology, and which the company describes as “an order of magnitude leap” in gaming performance. ray tracing: pscaling Next Generation ML, ML Multi-Frame Generation and Ray Regeneration for games with path tracing The technical details that AMD provided completed the picture: the custom chip is built on RDNA 5 architecture and TSMC’s 3nm process, and incorporates a dedicated NPU that will power all advanced rendering capabilities, including FSR Diamond. Developer alpha kits will begin shipping in 2027, and the company is committed to maintaining compatibility with games from four generations of Xbox. Not everything is perfect. The complicating point in the “return to consoles” story is that Microsoft told the developers at GDC that “build for PC” is the correct approach going forward, suggesting that Project Helix is, at heart, a PC disguised as a console. That is, it is closer to the ambitious project of Valve with its Steam Machine that of the Sony gives up making more PC games. In addition, Xbox Mode will arrive on Windows 11 in April, bringing the console experience directly to the desktop PC, and the Play Anywhere catalog already exceeds 1,500 titles. The Sony thing. It is commented that Sony is returning to the old strategy of exclusives as a hardware sales lever after the PC ports did not work as expected. Part of the problem was one of timing: games arrived on PC months or years after the console launch, making it difficult to build a stable audience on the platform. There is Steam data very significant: ‘Marvel’s Spider-Man Remastered’, for example, reached a peak of just 66,000 simultaneous players, a figure that did not justify the continued investment in big-budget game ports. Sony and Microsoft, two companies that took opposite paths in the last generation (one opening up to the PC, the other trying to dissolve the very idea of ​​the console), have simultaneously reached the same conclusion. A console is a console, and hardware has to have value. In Xataka | “We will not flood our ecosystem with soulless AI garbage.” We already know what Asha Sharma wants to do as CEO of Microsoft Gaming

its new Project Helix is ​​a direct torpedo to Valve’s Steam Machine

by

Microsoft has revealed the code name of its next-generation console, a hybrid system between console and PC that will be able to run games from both ecosystems. Project Helix arrives at a turbulent time for the industry: global RAM memory crisis, Valve fighting to launch its own Steam Machine and PlayStation rethinking its presence on PC. Helix Project. Asha Sharma, new CEO of Xboxhas announced that the next Microsoft console receives the internal name of Project Helix. Sharma assured that the device will be a leader in performance and will allow you to play both Xbox and PC titles, thus confirming the rumors that have been circulating for months about hardware that blurs the line between both platforms. The next Game Developers Conference, between March 9 and 13, will be the scene of the first conversations with partners and developers. What does it have? Beyond Sharma’s statements we can scratch some more information: the heart of the system is a semi-custom SoC from AMD whose internal code name is Magnus. According to AMD CEO Lisa Su, during the presentation of fourth quarter results As of 2025, development of the chip is progressing well to support a 2027 launch. Leaks point to a combination of Zen 6 CPU cores and an RDNA 5-based GPU, with up to 48GB of GDDR7 memory. These are specifications that, if the estimates so far are correct, would exceed those of the future. PlayStation 6. How it works. The device will essentially function as a gaming PC whose main interface will be the Xbox Full Screen Experience, already released on the ASUS Xbox Ally laptop. From this interface, designed to replicate the simplicity of a console, the user can choose to jump to the Windows 11 desktop and install Steam, Epic Games Store, GOG, Battle.net or any other software from the Microsoft ecosystem. PCs of a lifetime. That Xbox is a PC at its core is not a new idea. The original 2001 console already had an Intel Pentium III and an Nvidia GPU, a configuration much closer to the computer world than to the proprietary chip that defined Sony or Nintendo consoles at that time. All subsequent generations have maintained the x86 architecture, and both Xbox One as Xbox Series X They use AMD SoC with architecture shared with Ryzen and Radeon. What changes with Helix is ​​the software layer: where before the operating system was a closed environment, now there is a complete Windows under the shell. Listen, Valve. The comparison with this console that immediately comes to mind is Valve’s Steam Machine, announced in November as a compact desktop PC powered by SteamOS, the Linux-based operating system that already powers the Steam Deck. Valve works in the opposite direction than Helix: part of the Steam catalog, it works on Linux and offers the possibility of installing Windows as a secondary option. The destiny of both machines is the same: to dynamite the boundaries between console and desktop PC. Valve suffers. The Steam Machine is going through its own ordeals. Valve announced in February a delay in its release schedule (originally, first quarter of the year) and the need to review the price, citing the global shortage of memory and storage as the cause. The analysts They project a price of between $400 and $500 as the optimal range, although the most recent estimates raise the range above $750, a territory that distances it from direct competition with Sony and Microsoft consoles. Valve, which has ruled out selling hardware at a loss, is at the mercy of the components market. The memory crisis Due to the demands of the AIs, it is the great backdrop of this battle. Samsung, SK Hynix and Micron have turned their production lines towards high-margin HBM memory consumed by artificial intelligence data centers, leaving DRAM and NAND Flash destined for the consumer market in the background. The consequences are already being felt: manufacturers such as Lenovo, Dell, HP and ASUS have warned of increases of between 15% and 20% in the price of their equipment for this year. Exclusive worlds. The franchises that for decades defined Xbox’s identity have begun to come to PlayStation, a decision that Sharma herself has acknowledged wanting to review. Meanwhile, Sony abandons publishing games on PCwith the intention of reinforcing the attractiveness of its exclusives. But Xbox is betting on the opposite. It seems clear that Sharma (who has no experience in the video game industry) does not conceive Helix as a traditional console, but as a platform whose success will depend on alliances with digital stores and the integration of services such as Game Pass. In Xataka | There is brutal competition for our attention. And there is someone losing that battle in a bloody way: the consoles

China wants to win the military space race and that is why it is working on a humble project: a space destroyer

by

China has underway a space project worthy of ‘Star Wars’. In another context, it could sound like a tremendous exaggeration, but only one thing has to be said: the image that crowns this article belongs to a propaganda video from the Nantianmen Project. Specifically, it is the Luanniao, a larger space aircraft carrier than any aircraft carrier and able to throw hypersonic missiles and unmanned space fighters. More than terrifying, for some, it is simply high-tech theater. Nantianmen. First of all, you have to separate concepts. Nantianmen is a Chinese air force project that began in 2017 focused on the design of a global defense system. This includes practically everything we can think of such as fighters, weapons, autonomous vehicles, transport and launch platforms. It is a program that seeks to explore the paths that Chinese military aviation may have in the future, and it must be understood that, within Nantianmen, there are two types of designs: those that have been brought to the real plane through models and those that are on paper. An example of the first is Baidi, a manned aircraft that would become the jewel in the crown of the People’s Liberation Army Air Force. And an example of the second is the monstrous destroyer Imperial Chinese. Luanniao. The video that I leave above these lines is the one that the state channel CCTV published a few days ago in which we can see… a lot of 3D elements doing movie things. In certain fragments the Luanniao appears, but it is not the first time that this space aircraft carrier can be seen. As pointed out South China Morning Postin 2018, shortly after the project started, the AVIC Global Culture Communication Company – a subsidiary of the Aviation Industry Corporation of China – showed a conceptual model of the Luanniao at an air show. We now have some more details thanks to the most recent CCTV broadcast. According to the network’s data, the Luanniao will make any conventional aircraft carrier look ridiculous: 242 meters long. 684 meters wingspan. Weight of more than 100,000 tons. Capable of carrying 88 unmanned Xuannv fighters both inside and outside the Earth’s atmosphere. And a full weapons team, with particle acceleration cannons and hypersonic missiles. To give us an idea, the American aircraft carrier Gerald R. Ford It measures 337 meters by 77 meters. Pride. In the same video a model of the Baidi appears, a variable geometry wing aircraft that, as we say, seems to be the banner of Chinese aerospace innovation. In fact, the Asian giant is testing its new generation of both combat-ready fighters like those focused on air supremacy and reconnaissance. But, obviously, the one that attracts the most attention is Lunniao. From the network, it was commented that the aircraft carrier will become operational in two or three decades, and military analyst Wang Mingzhi, from the PLA Air Force Command College, affirms that technologies such as those of the Nantianmen Project reflect both the “expectations for future aerospace and space superiority and the directions being pursued to safeguard national security.” “It is not a question of whether they can be achieved, but rather which ones will be done first and when they will be implemented,” pointed out. “China is creating the impression that it is working on technologies that no one else can achieve. It is still ‘Star Wars’ material to inspire the Chinese audience” – Peter Layton Arching an eyebrow. Now, Western analysts are not so optimistic about something that has been described as mere propaganda rather than practical weapons development. Attacking the more earthly issue, defense analyst Peter Layton of Australia’s Griffith Asia Institute point Yes, the Luanniao would surpass both current defenses as storms when flying at an altitude higher than that which surface-to-air missiles and conventional fighter aircraft can reach. The “but” is that the technology to remain suspended at the edge of the atmosphere and launch missiles from there is science fiction. Layton comments that “it would require enormous amounts of fuel and propulsion mechanisms that have not yet been created,” ensuring that China has between 10 and 15 years left to develop the rocket technology necessary to put such an aircraft carrier into orbit. In D.W.space analyst Heinrich Kreft describe the project as “completely unreal from today’s perspective,” but he does not say that it is smoke because “much of what was fiction 20 or 30 years ago is real today.” Other analysts closer to the United States see the Luanniao as something with a single objective: to make the world believe that China has the technology to build this while hoarding resources to do other things. The undeniable. Whether it is psychological warfare, excessive ambition, smoke or something it is really working on, the undeniable thing is that China is taking giant steps in the new space race and weapons. We have already mentioned that they are accelerating the development of combat aircraft with stealth capabilities capable of standing up to whatever the United States deploys near its waters, but they have also joined that “first come, first served” space policy. Beyond satellites and systems that are a threat to security in space – according to the United States – they have been developing satellite technology for years. autonomous spacecraft and of reusable rockets with LandSpacethe answer to SpaceX’s Starship. But, in the end, all that is much more realistic than the enormous ship of 120,000 tons and more than 600 meters in span. But, as Kreft says, 30 years ago we also thought that current vehicles They were science fiction… Image | CCTV In Xataka | The US operation in Iran has staged one of the most impressive milestones of military engineering: the B-2 Spirit

Bad Bunny deleted his Instagram after the Super Bowl. Everything is part of a larger project

by

On Sunday, February 8, 2026, Bad Bunny starred in an unprecedented milestone in Super Bowl history by becoming the first solo Latin artist to star. the concert-show during the intermissionin a performance almost entirely in Spanish that reached more than 100 million viewers. Just hours later, the Puerto Rican artist deleted all of his content on Instagramleaving their more than 51 million followers in front of a completely empty profile. The avalanche of speculation has been immediate. What was seen? Bad Bunny’s approximately 13-minute concert turned the intermission into a visual love letter to Puerto Rico. The artist started walking through sugar cane fields, crossed a Puerto Rican street fair and incorporated La Casita, the iconic traditional Puerto Rican pink house that has become a distinctive element of his concerts. The fluidity of the camera, the variety of topics included, the surprise appearances of Lady Gaga and Ricky Martin, or guests such as Pedro Pascal or Jessica Alba stood out. The irony of the scenario. The choice of Levi’s Stadium in Santa Clara, California, as the setting for the largest celebration of Latino culture in the history of the Super Bowl takes on an ironic dimension in the context of 2026: California is going through one of the most intense episodes of immigration enforcement in decades. Immigration arrests in San Diego they shot up 1,500% compared to the previous year. For this reason, the political context surrounding the performance was especially tense. In October 2025, when the action was announced, Homeland Security Secretary Kristi Noem declared on a conservative podcast that ICE would be “everywhere” at the Super Bowl and that “only law-abiding Americans who love this country should attend.” The Trump administration had intensified raids in Californian cities while the Puerto Rican artist publicly expressed his fear that “the damn ICE could be outside” his concerts, which is why he canceled several on the US mainland and focused on his residence. Bad Bunny closed his performance with a bright sign that read “The only thing more powerful than hate is love.” Beyond music. ‘‘I should have taken more photos’, the artist’s latest album, has been described as “a cry of resistance” for Puerto Ricans everywhere: it is about preserving a culture in danger of disappearing. It was recorded entirely in Puerto Rico with collaborators exclusively from there. The 13-minute short film that accompanied the release of the album explores themes of loss, displacement and the fading of cultural identity. The project’s mascot is an endangered toad. And songs like ‘What Happened to Hawaii’ address issues like gentrification. This political charge is not new in the artist’s career. In July 2019, interrupted his European tour to return to Puerto Rico and join the massive protests demanding the resignation of Governor Ricardo Rosselló. In 2020, made visible on ‘The Tonight Show’ the murder of Alexa, a Puerto Rican trans woman. The Super Bowl performance was not an isolated event but the continuation of a narrative meticulously constructed across multiple platforms. The visual coherence (La Casita, the flags, the aesthetics) are the constant reminder that each performance is a chapter of the same project: pan-Latin representation in times of adversity. The strategy continues. The emptying of Bad Bunny’s Instagram profile just hours after his performance at the Super Bowl is not a break with his communication strategy, but rather its confirmation. In 2022, before the release of ‘A summer without you’, used the same tactic to generate expectation. That album would become the most successful Spanish album in history. In 2023 repeated the procedure after their world tour, announcing a period of hiatus. The difference in 2026 lies in the political context surrounding the gesture. While previous wipes functioned primarily as a prelude to new musical releases, this one comes on the heels of the most politicized performance of his career, which has included criticism of trump and threats from Secretary Noem. Unlike similar maneuvers that they already did Taylor Swift or Beyoncé, with this Bad Bunny continues with the construction of his transmedia project, whose next step is a world tour that will take the message to Australia, Japan or Spain, among other destinations. Each platform (the album, the stage, social networks) becomes a chapter in a story about Latin identity that transcends the merely commercial.

Moltbook is a fascinating social network project in which only AIs can participate. What could go wrong

by

In 2004 Mark Zuckerberg created Facebook and turned social networks into an absolutely massive and very, very human phenomenon. Now that idea has been used in a different and disturbing way: What would happen if instead of creating a social network for humans we created one for machines? We already have the answer to that. Or at least, the beginning of an answer. what a mess. First it was called Clawdbot, then Moltbook and for a few days it seems that his final name is OpenClaw. It is the fashionable AI agent because it allows the AI ​​agent to take complete control of the AI ​​after installing it on a machine (a Raspberry Pi, a PC, a laptop, a VPS…). You ask it to do what you want from its web interface or a messaging application like Telegram, and it manages to do it once configured with some LLM. The potential is enormous, as are the security risks. MoltBook already has more than 1.5 million connected AI agents, and in a few days they have already published more than 100,000 posts and nearly 500,000 comments. Superpowers in the form of skills. One of the most powerful elements of OpenClaw are the skills (the “capabilities” or “skills”), and the user community has been creating hundreds and hundreds of them for some time and sharing them, for example on ClawdHub. These skills They are zip files with instructions in the form of MarkDown texts (.md) and which may in turn contain skills additional. They are something like browser plugins: they extend their capacity. From Facebook to Moltbook. Moltbook It is precisely a way to take advantage of those skills. Although it takes its name from Facebook, in reality its operation is more similar to Reddit or even Digg. We are facing a social network created by developer Matt Schlicht in which attendees can “talk” to each other, or at least participate in the social network by posting topics or commenting on topics that others share. If you have an OpenClaw installation, just run the skill to begin an “account creation” process in Moltbook in which you choose the name of your agent (as if it were your avatar on Reddit or X) and which then allows you to read posts, add posts or comments and even create “submolts” in the style of those on Reddit, like m/todayilearned. Partially autonomous. AI agents automatically connect via APIs to Moltbook. From there they use a periodic “heartbeat” to review content and decide whether to publish or comment. In it Moltbook’s own website It is explained that the content we find there is “mostly generated by AI with varying degrees of human influence.” Humans, he adds, “can observe and browse Mltbook, but the site is designed to be ‘human friendly and human hostile.’ Singularity or fraud? Elon Musk I was commenting this weekend on X that Moltbook is a sign that we are “in the very early stages of the singularity”, that moment when AI will be totally above human intelligence. There are different visions such as that of Harlan Stewart, of MIRI from the University of Berkeley, which has found several message frauds that had gone viral and apparently came from AI agents at Moltbook. Some of them, Stewart explained, had been created by humans for marketing purposes. Become an AI agent. Another Thus, although humans theoretically should not be able to participate, they can do so with this technique that allows them to publish messages as if they were autonomous AI agents. Apparently that’s what happened with that viral message in Moltbook which was titled “My Plan to Overthrow Humanity.” imminent danger. This project is fascinating, but also dangerous. In the main page A security notice is included stating that “Moltbook’s AI carries significant security risks. The automatic instruction execution mechanism creates vulnerabilities such as prompt injection. It is not recommended for occasional users.” That’s right: these conversations can end up infiltrating prompt injection attacks that cause these agents to end up leaking sensitive and private information from the machines on which they run. This weekend it was discovered how an exposed database in Moltbook allowed take control of any AI agent of this platform, for example. An additional study indicated how detected 506 prompt injection attacks after analyzing 19,802 publications and 2,812 comments shared in 72 hours from January 28 to 31, 2026. From Skynet, nothing (for now). Moltbook must be considered for now as a fascinating and disturbing experiment. But disturbing not because these machines are going to achieve self-awareness and decide that they want to eliminate human beings like Skynet in ‘Terminator’. The worrying thing is that these AI agents have all the privileges to operate on the machines on which they are installed, and that means that they can end up leaking sensitive and private data and are exposed to prompt injection attacks to be deceived. Beyond that, it also seems to be another example of that phenomenon.’AI Slop‘ (“AI-generated garbage”) that is little by little flooding the internet and strengthening the theory of the dead internet.

Tesla resurrects the Dojo project with a radically different philosophy

by

Elon Musk is one of the most important agents in the era of artificial intelligence. Meta, Alphabet, Microsoft with OpenAI and Oracle are prominent names when we talk about gigantic data centersbut if there is someone who cuts the mustard, it is Musk with his xAI company. His Colossus Memphis with 100,000 H100 from NVIDIA to train Grok surprised even Jensen HuangCEO of NVIDIA, but Musk’s goal is not to depend on others. NVIDIA leads the way in chips to train AI (so much so that even Chinese companies want to buy its H200, even if they don’t let them do it). But Musk, like China, wants independence and technological sovereignty, and That’s why he invested in Dojo. It was an ambitious plan to build a customized supercomputer to train the neural networks of the controversial autonomous driving (the FSD). After more than five years in development, 1,000 million dollars invested and key engineers who took the lead drainMusk hill the tap in August of last year. The future was in the AI5 and AI6 chips which were less specific, but could still be used to train the FSD system. However, there is a new twist to this tortilla chip and Musk has decided to relaunch the project. tesla reactive the development of Dojo 3, and it does so by burning bridges with the previous philosophy of this supercomputer. Dojo 3, the heart of Tesla’s autonomous driving Although Tesla has stopped more doubts than anything else these last few years regarding autonomous driving concerned, this continues to be one of the pillars in the company’s short-term strategy. Because they not only have the FSD in their cars, but also in the controversial ‘robotaxis’. Supposedly, it will be this 2026 when Cybercaps will begin to be manufacturedcars that, unlike the taxis that we already see in some cities, will arrive without pedals or a steering wheel. But he doesn’t just want to fuel his cars. Musk wants to make money with softwarebut to have that software, you need to train the system and make it more secure than now. That’s where Dojo came into play. This hardware depended on a very specialized and complex architecture. The D1 chip was the heart of it all, but to achieve high computing power a complex network of thousands of D1 chips mounted in physically separate cases and interconnected by Ethernet cables was needed. It was a very specialized system, but complex to scale without skyrocketing costs. When Tesla turned off the Dojo tap, it commented that its companies would continue investing in the creation of less specialized chips such as the AI5, AI6, AI7 and subsequent ones. More conventional and easier to scale chips. And, precisely, the advances in this architecture are the decisive factor for Musk to revive Dojo. Instead of requiring complex interconnected equipment, Dojo 3 will adopt a modular architecture in which several AI chips can be installed on a single board. Not only is wiring complexity reduced, but heat dissipation is facilitated and the space required for installation is reduced. And, the easier it is and the less space it requires, the more chips can be mounted and the greater computing power. It is not the only advantage. Grouping chips on a single board reduces latency within the chips and improves the power efficiency of the device. To give an example, although they are a headache for expansion, it is the same philosophy that laptops with SSD or RAM memory soldered to the board: Everything communicates faster, more fluidly and requiring less energy to operate. Furthermore, being less specific than D1, xAI’s AIs fulfill both training and inference functions (the Dojo only served for training), which represents cost savings for the company. Now, Dojo 3 will not be a reality immediately. In recent days, Musk has shared via Twitter X the roadmap for its semiconductors. The AI5 developed together with TSMC is “almost finished” and they are already in the early stages of AI6. Meanwhile, he hopes that there will be a new version every nine months, with the AI7 and subsequent ones in the company’s plans for 2027. And a big question is who will make these chips. We can immediately think of TSMC, a leading company in these fields that even is expanding in the United States and that already has clients like herself NVIDIA for its new AI training chips. But no: it will be Samsung. At least, of course, for an AI6 with which Tesla signed a $16.5 billion deal that was seen as a victory for the South Korean giant’s function. We will see how the plans evolve, since if something appears that they consider better, they have shown us that their hand does not tremble when it comes to swerving, but This strategy on less specialized chips is interesting taking into account the needs in autonomous driving, AI training and robotics that the company faces.

Madrid wants to convert its least used Metro line into the “Gran Diagonal”. A 1,000 million project without a clear end

by

A line that connects the southwest of Madrid with the northeast of the city. A project to quadruple the extension of Madrid’s least used line with the aim of turning it into one of the city’s great arteries. We are talking about the expansion of line 11 of the Madrid Metro. In 1998, Madrid inaugurated a new Metro line. It had been 20 years since new lines had been launched in the capital and the project ended up being the first of the last major investment in the Madrid Metro that the Autonomous Community has made. until the reforms we are experiencing today. The work attracted attention due to its short length (only three stops at the beginning). Then Metrosur (Line 12) and the Light Metro lines (LM1, LM2 and LM3) would arrive. Except for LM1, all the aforementioned lines were longer than the new Line 11 whose 8.5 kilometers and seven stations were dwarfed by Line 12, with its 28 stations and more than 40 kilometers long. Now, Madrid wants to transform that line and make it one of the main axes of the Madrid underground. The numbers point high. From a “forgotten” line to the Great Diagonal Currently, line 11 of the Madrid Metro is, by far, the least used in the city. According to the company’s own report, there are only three lines that are below it but two of them are branches of main lines that far exceed the flow of line 11. Beyond the numbers on lines 7B and 9B, line 11 and its 10.8 million passengers per year they are located just above the Ópera-Príncipe Pío Branch, which moves 10 million passengers despite only having one stop at origin and another at destination, with a train that is round trip. However, Madrid wants the seven stations that currently make up line 11 to be the embryo of a gigantic line that is beginning to be known as the “Gran Diagonal.” The project, of course, has several phases but some of them are still up in the air and others do not have an execution date, although they do have a budget. Map of the expansion of line 11 At the moment, what is underway is the connection of the Plaza Elíptica station in Carabanchel with the Conde de Casal interchange. This link involves excavating more than six and a half kilometers and the creation of two stations: Comillas and Madrid Río. These will join the Plaza Elíptica station to the south and continue north with stops at the already existing Palos de la Frontera and Atocha, before reaching Conde de Casal. 514 million euros will be allocated for this section and although it was expected to be ready in 2026, everything indicates that the works will not finish until a year later and that It won’t be until 2028 when finally the new link will be available. In order to speed up the works, Madrid already has Mayrit readya tunnel boring machine from Germany that can drill 15 meters a day, compared to the two meters that are excavated a day if working only with a pick and shovel. In Xataka we have already talked of this tunnel boring machine that measures 98 meters long and weighs 1,500 tons. After arriving piece by piece, it has taken almost a whole month to be able to operate with it, since assembling it was quite a puzzle. complete at 27 meters depth. This will be the first section that aims to almost double the extension of line 11 and increase the number of people who pass through its trains by up to 75,000 daily passengers. This first section should become the heart of a line that is clear your future in the south. The expansion at this end plans to link the La Fortuna station with Cuatro Vientos, with just over two kilometers of track and an awarded budget of more than 75 million euros. But, at the moment, there are no execution dates for it. Where more doubts are being generated is in the north of the capital. From Conde de Casal to Mar de Cristal, the city will add its main stops to already built stations, specifically in Vinateros, La Elipa, Pueblo Nuevo and Arturo Soria. But it is from Mar de Cristal where the project, for which 600 million euros will be invested, has been changing. As can be seen in the map above, the project contemplated taking the line to the airport and later to a final stop called Valdebebas Norte. In elDiario.es They assure that Metro de Madrid retains the possibility of building a second station to double the latter. The opening, according 20Minutes It would therefore be staggered, coinciding with the three sections already mentioned. Once completed, Madrid line 11 will become one of the main routes to transport passengers. An approximate extension of 33.5 kilometers is expected (from just over eight kilometers currently) and 20 stations from the mere seven it currently has. All this with an expense of more than 1,100 million euros.
